A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Longest documented coastal migrations of shortnose sturgeon

open access: yesJournal of Fish Biology, EarlyView.
Abstract The shortnose sturgeon (SNS; Acipenser brevirostrum) is a United States federally endangered diadromous species. Although SNS spend much of their time in riverine habitat, inter‐river migrations have been documented in northern populations.

Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

open access: yesJournal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

The cognitive role of concept variability

open access: yesMind &Language, EarlyView.
I present and defend concept variability, the view that concepts can admit of indefinitely many variations and changes in their representational contents without thereby losing their identity. I argue that the variability of concepts is central to their role in enabling cognition, and thus that a concept's content variability is, despite philosophical ...

RESEARCH REGARDING THE EVOLUTION OF CORPORAL WEIGHTES AND FOOD CONVERSSION ON JUVENILE OF SIBERIAN STURGEON (Acipenser baeri) RAISED IN RECIRCULATING SYSTEM

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The research was performed within the recirculating aquaculture system for sturgeon growth, in Banat's Universsity of Agricultural Sciences and Veterinary Medicine from Timisoara, on 2851 juveniles of Siberian sturgeons (Acipenser baeri), aged between ...

Tackling Poverty Across the United Kingdom. Devolution, Difference and Discourse

open access: yesIPPR Progressive Review, EarlyView.
ABSTRACT The UK welfare state is often considered as being highly centralised, yet the design and administration of UK social security involves significant spatial variations in law, policy, and practice. As such, where you live in the UK can affect the value of benefits and cash transfers you are entitled to, as well as how you experience benefit ...
